S55 E-TRONIC TUNER for BMW F8X M3 & M4
Our E-Tronic tuner is one of the most popular performance mods in the F8X M3/M4 community. The E-Tronic is a multi-channel controller that integrates both RPM and MAF signals to allow adjustment of boost under all RPM ranges and fuel maps at partial load. Included with the E-Tronic are 3 built in preconfigured settings, meaning all the user has to do is plug the device in and they’ll be set, no adjustments or splicing needed.
